tab only completes the command name not its previous arguments/parameters.

to also autocomplete the complete command with arguments from history set the below keybinding.

Set-PSReadlineKeyHandler -Key UpArrow -Function HistorySearchBackward
Set-PSReadlineKeyHandler -Key DownArrow -Function HistorySearchForward

Now, type few characters of command name and use up/down arrow to autocomplete this command (with arguments) from history.
